I highly doubt that they are using a chinese dialect for the doctors name. Seeing that most japanese people do not know chinese. Probably a more traditional form of japanese characters. But hey, I do not know that much japanese in the first place.
If it is not too hard, can you post the whole second story, unless it is waay too long. Then I would not worry about it. Look at me, I tried to post a 30 some meg manga once. People were whinning to no extent. (I want it, because it looks good enough to translate the important parts.)
